Claudius vs Tigranes II of Armenia

After Caligula's assassination, Claudius was found hiding and proclaimed emperor by the Praetorian Guard. The Senate reluctantly accepted him, marking the first time the Guard directly chose an emperor.

Claudius initiated the construction of a new harbor at Ostia to improve Rome's grain supply. The project included a large artificial basin and a lighthouse, facilitating trade and food imports.

Claudius ordered the invasion of Britain, sending four legions under Aulus Plautius. He later visited the island to accept the surrender of the British tribes, incorporating southern Britain into the Roman Empire.

Claudius extended Roman citizenship to certain provincial communities, particularly in Gaul. He also admitted Gauls into the Senate, promoting integration of the empire's elites.

Claudius married his niece Agrippina the Younger, who then maneuvered to have her son Nero adopted as Claudius's heir. This marriage led to Claudius's eventual poisoning and Nero's succession.

Tigranes II was crowned King of Armenia after being released as a hostage by the Parthian king Mithridates II. He immediately began expanding Armenian territory, conquering Sophene and other regions, laying the foundation for his empire.

Tigranes II conquered the remnants of the Seleucid Empire, annexing Syria and Cilicia. This expansion brought Armenia to its greatest territorial extent, stretching from the Caspian Sea to the Mediterranean, and made Tigranes a major power in the Near East.

Tigranes II founded the city of Tigranocerta as the new capital of his empire. The city was built with a mixed population of Armenians, Greeks, and others, and became a major Hellenistic center of trade and culture in the region.

Roman forces under Lucullus defeated Tigranes II's army at the Battle of Tigranocerta. The defeat led to the loss of Tigranes' newly conquered territories and the sacking of his capital, marking the beginning of the decline of the Armenian Empire.

After further defeats, Tigranes II submitted to the Roman general Pompey. He was allowed to retain Armenia proper as a Roman ally but was forced to give up all his conquests, including Syria, Cilicia, and Sophene, reducing Armenia to its pre-imperial borders.
